The First Mission of Capitalism II's Entrepreneur's Campaign. The Mission requires you to dominate the Computing Industry and also make annual revenues of $400 Million Dollars. The mission is quite easy though (although it took me a few tries).
The thing that helps the most is you have researched two technologies that no one else has, namely the Palm Computer and the Notebook Computer. As such, you can very easily create a monopoly with these two computers and charge a fortune for them, and no one can stop you mwuhahahahaha.
Once you have those set up and you're selling them in Rome and Sydney, you can use the obscene profits from them to build factories to create your printers and desktop computers, which are the other two items in the computing industry. If you move fast enough you can dominate all four products before your competitors really get started.
